So, I was watching the Unlock the Magic episode: The Ultimate Bad Seed, and Tender-heart said something that got my fan gears turning. He said, "The only safe place for all that badness is back in its original vessel." And that got me thinking. What if Bluster wasn't bad originally, he became corrupted by an immense source of badness?
Also, it got me thinking of an AU to write about. I love making fan-theories.
